Another antipattern, not specific to standups: everyone sitting around absorbed in their laptops not paying attention to anything until their turn comes around.

Another antipattern, not specific to standups: everyone sitting around absorbed in their laptops not paying attention to anything until their turn comes around. (Another reason to actually stand during standups, I suppose.) Another mentioned in this thread -- if you have distinct groups within a team who are working on mostly separate projects, don't combine their standups. Otherwise, you just encourage half of the attendees to tune out (exacerbating the situation above.)
